Micrel, Inc. ECL Pro™ SY100EP16VS 5V/3.3V 2.5Gbps VARIABLE OUTPUT SWING DIFFERENTIAL RECEIVER ECL Pro™ SY100EP16VS FEATURES ■ 3.3V and 5V power supply options ■ Fast output transitions <160ps tr / tf ■ Guaranteed operation over –40°C to +85°C temperature range ■ Functionally equivalent to SY88927V and SY10EP16V ■ Variable output swing from 100mV to 700mV ■ Available in 8-pin (3mm) EPAD-MSOP package ECL Pro™ DESCRIPTION The SY100EP16VS are differential receivers with variable output swing. The devices are functionally equivalent to the EP16V devices with an input that controls the amplitude of the outputs. EP16VS is commonly used as VCSEL laser driver. The operational range of the EP16VS control input is from VBB (max. swing) to VCC (min. swing). Simple control of the output swing can be obtained by a variable resistor between the VBB pin and VCC with the wiper driving VCTRL. The EP16VS provides a VBB output for either singleended use or as a DC bias for AC coupling to the device. The V BB pin should be used only as a bias for the EP16VS as its current sink/source capability is limited. Whenever used, the VBB pin should be bypassed with a 0.01µF capacitor to VCC (in PECL mode). Under open input conditions (pulled to VEE), internal input clamps will force the Q output LOW.

Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of ≈40 when output has a full swing. Note 2. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between VPP (min.) and 1V. The lower end of the CMR range varies 1:1 with VEE. The numbers in the spec table assume a nominal VEE = –3.3V and VCC = 0V. Note for PECL operation, the VCMR (min.) will be fixed at 3.3V – |VCMR (min.)|. Note 3. Output at full swing.
